If people are still saying the events are too easy for some people, maybe they could add a 4th difficulty to the island, "ultra" mode or something. It could be difficult enough that you really need a team of full BLB LR to have a shot, but the rewards/drops would be increased as well. Of course then lower players will probably complain that it is a feature for cash players and is out of reach...

Like in the current stage if you inflict say about 800 damage, he counters and re-inflicts only 1 damage. But in my suggestion he would counter inflict 800 damage only apart from regular attack. So like if you inflict 2000 dmg, he'll counter inflict 2000 damage to the team.
